Kris graciously invited Lamar to the Kardashians’ Thanksgiving dinner, but he says he will only attend if his father can come too. Now Lamar’s ultimatum has sparked a huge fight between himself and Kris, a source tells HollywoodLife.com EXCLUSIVELY.

Despite Lamar Odom‘s dysfunctional relationship with his father, Joe Odom, he still wants to spend time with him on Thanksgiving — along with his wife, Khloe Kardashian, and her family. But will matriarch Kris Jennerbe able to forgive Joe and open her doors to him after he viciously dissed the entire Kardashian clan? Read on for all the EXCLUSIVE details.

“Lamar wants to be with Khloe and the rest of her family for Thanksgiving, no question. But, he also wants his father to be part of the meal because he’s family too. Lamar is caught up because he can’t be in two places at once,” a source tells Hollywoodlife.com EXCLUSIVELY.

Although Khloe, 29, and Lamar, 34, aren’t on the best of terms, she still understands his concerns — but unfortunately it’s her momager, Kris Jenner, 58, who has a bone to pick with Joe.

“Kris isn’t over what Joe said about her and the rest of her family,” the source reveals.
